Defrost frozen raspberries. Select fresh berries, wash and drain if necessary. Soak gelatine in cold water.
Separate eggs. Beat the egg yolks, sugar, 1 pinch of salt and cinnamon with the whisks of the mixer until thick and creamy. Stir in lemon juice.
Warm the wine. Squeeze the gelatine and dissolve in the hot wine. Pour into the egg yolk mixture while stirring. Chill for 5-8 minutes until the cream begins to gel.
In the meantime beat the egg whites until stiff. Loosely fold the beaten egg whites with plenty of air into the gelling cream. Pour into four dessert glasses and chill for about 2 hours.
In the meantime, puree the raspberries and vanilla sugar and pass through a fine sieve. Serve the Berlin air with raspberry sauce.
